SERVICE APPARATUS FOR MALT LIQUORS.

SPECIFICATION forming part of Letters Patentl No. 348,668, datedSeptember 7l 1886.

Application filed March 3, 1886. Serial No. 193,862. (No model.)

To all whom t may concern.-

Be it known that I, JOHN I). GRUBER, a citizen of the United States, anda resident of Jersey City, in the county of Hudson and State of NewJersey, have invented certain Improvements in Service Apparatus for MaltLiquors, of which the following` is a specification.

My invention relates to an apparatus designed, in the main, for servingthat class of malt liquors known to brewers as ale/7 although it may beemployed for beers classified under other names, and especially those ofan unctuous character, which readily foam when drawn.

It is well known that when new ale is drawn from the cask it isnsually'allowed to stand in a measure for a time, in order that the foammay break up, as it is very difficult to draw it directly into theglass. This use of an open measure is very uncleanl y, and in summertime attracts flies and other insects.

The object of iny apparatus is to provide means for drawing the ale orvother liquor solid (or with very little foam) directly into the glass;or at will the liquor may be drawn through the same faucet directly fromthe cask into a vessel or glass; or, it may be drawn partly directlyfrom the cask and partly from the receptacle of my apparatus, all aswill be hereinafter described.

An apparatus embodying` to some extent the characteristics indicatedabove is shown in my Patent No. 2l0,0l8, dated April l2, 1881.

The novel features of my invention will be hereinafter fully set forth,and carefully defined in the claims.

In the drawings which serve to illustrate my invention, Figure l is ageneral sectional elevation of my improved apparatus. Fig. 2 is adetached sectional view taken in the plane indicated byline 22 in Fig.l. Fig. 3 is a detached sectional view taken in the plane indicatedbyline 3 3 in Fig. l. Fig. 4 is a longitudinal sectional view of thetwo-way faucet F, whereat the liquor is drawn.

Before proceeding to describe my invention, I will say that herein Ihave shown the servicefaucet connected close to the receiver orreceptacle ofthe apparatus, for convenience of illustration; but this isnot essential. They may bev separated to any desired extent, and bearranged with respect to each other in any way that is found mostconvenient.

A represents a receiver, which I usually make of sheet metal and ofcylindrical form. It may, however, be made of any form and of anysuitable material.

B is a glass-tube gage, connected to the receiver at` its top and bottomin the manner of a tube gage for a steam-generator. This gage hasgraduations formed by marks a a, and designated by the letters Pt., Qt.,arranged in alternate order, as shown. These indicate both the quantityof the liquor at any time remaining in the receiver, and also the amountin pints drawn from it at any time. I usually employ different-coloredpaints for marking the pint and quart graduations, so that they may bereadily distinguished from each other.

C is the eduction or 'delivery tube ofthe receiver, which depends to ornearly to the bottom of the receiver, and has a screw-threaded boss, b,which screws into the top of the receiver onto a packing-ring, c,whereby a gastight joint is produced. To the upper outer end of theyeduction-tube is coupled by a detachable union, D, the delivery-pipe E,which leads to the two-way service-faucet F, which will be moreparticularly described hereinafter.

On the crown of the receiver is mounted an adjustable pressure-valve, G,whereby, when the gaseous tension in the receiver exceeds apredetermined point the gas is allowed to escape and relieve thepressure. This device consists of a valve, d, which rests en a seat, e,and has a stem, f,whieh passes out through the crown of a screw-cap, g,which screws down into an internallyscrew-threaded flange around thevalve-seat. Between the valve and this cap is arranged a spring, h, thetension of which is regulated byscrewing the cap g up or down, as willbe well understood.

I will now describe the induction portion of my apparatus.

II is the pipe leading from the cask of ale, which may be placedanywhere, as in the cellar, for example. I have herein shown this pipeas branched at the coupling I, the main pipe going directly to theservice-faucet F, and the branch H going to the receiver through apressure-regulator, J. Both ,pipes H H might lead directly from' thecask, but I prefer to employ one main pipe, H, for the sake of economyand convenience7 and to couple the branch H to it by a union orcoupling, I which I will describe.

K is a cock, usually of brass,which is placed in branch H', usually oflead pipe, and which controls the passage in said pipe. On the end ofone of the arms i of cock J is fixed or integrally formed a plate, j,having a half-round groove in its face to receive pipe H (also of lead)and flanges with screw-holes therein. Another similar plate, k, embracesthe pipe H on the opposite side, and screws Z Z, passing through theflanges of the plates j k, cause them to clamp the pipe H firmly. A holeof the proper size is cut in the side of pipe H, next Yto platej, and ashort coned tube, m, on plate j, which may be the prolongation throughthe plate of the arm 'i of cock K, enters said aperture in pipe H, andthus opens communications between pipe H and branch H. Of course pipe Hmight lead to the cask and pipe H from the branch. rllhe ale on its waythrough pipe H to the receiver A must pass through the pressureregulatorJ, which I will describe with reference to Figs. l and 3. To the inlet aof the regulator is coupled the pipe H. rlhis inlet is prolonged insideof the shell 0 of the regulator, is closed at its inner end, and has anaperture, p, which is closed by a valve, q. This valve has two arms, 1'r, which pass up alongside ofthe inlet-tube, and are e0nnected to thevalve-stem s. Between disks on the stem is clamped a rubber diaphragm,t, which forms a partition across the shell o. On the valve-stem, andpressing on a ilanged nut, a, on same, is a spring, c, the upper end ofwhich takes under a screw-cap, w, that screws V.own into an aperture inthe top of shell o.

,fr is merely an external cap perforated to admit air to the upper sideof the diaphragm and designed to protect the regulator J from accidentalinjury or disarrangement.

y is the outlet of the regulator, which is coupled by areadily-detachable union to the induction-tube M of the receiver A. Inorder that the ale may enter the receiver in fine iets and be deliveredin an upward direction, i usually slope or bevel the inner end of thetube M on the upper side and cover this end with a perforated plate,

Referring to Figs. l and 4, I will now describe the construction of thetwo-way faucet F. In the shell l is formed the usual conical bore toreceive the plug 2, and also the axial outlet-passage 3, and twoinlet-passages, 4 and 5. These inlet-passages are connected,respectively, each with one of the pipes E and H, usually through themedium of couplingtubes 6 and 7, which are arranged in the hollow arm Sof the faucet.-. The plug 2 is usually cored out or formed hollow at thepoint where it passes through the shell 1, and it is provided with awide port, 9, which is always in coincidence with the passage 3, as theplug 2 is or should be provided with stops, in the usual way,- to limitits axial rotation. The plug 2 also has a narrow port, 10, opposite theport 9, which former may, by the axial rotation of the plug, be placedtocoincide with either one of the passages 4 5, or be placed between them,as seen in Fig. 4. Vhen the plug stands as seen in Fig. 4, I prefer toarrange the crosshandle 11 of the plug to stand at right angles to thefaucet-axis, as shown. In this position the faucet is closed.

I will now describe the'operation ofthe ap paratus, premising that pipeH is connected below to a cask of ale under gaseous pressure, and thatfaucet F is closed, as seen in the drawings. The tension of spring eover the diaphragm of pressure-regulator J is regulated by screwing downor up the cap w, and the same is done to the spring of the regulator Gon the receiver A. 'When the cock K is opened, the ale, under pressurefrom the Cask, will ow through pipes H and H, and enter the shell 0 ofthe regulator J through port p, depressing valve q, in order to force apassage, and will flow thence through outlet y and into the receiver Athrough the jet apertures In passing through the regulator J, thegaseous tension will be reduced and made uniform. 'Ihe degree of tensionin the receiver will be regulated by the spring c. The pressure tendingto open valve q is equal to the tension in the pipe H', and this isopposed by an upward pressure on the diaphragm t, which is equal to thepressure in the receiver. As the diaphragm is many times larger in areathan the port p, it follows that a moderate tension in the receiver willclose the valve q against a much greater pressure 011 the valve, tendingto open it; but the tension of the spring c is opposed to the tension inthe receiver, and consequently the difference between the initialtension and that in receiver A may be regulated by the spring c. This isgenerally effected primarily, and allowed to remain without change; butthe tension in the receiver may be conveniently and readily reduced orincreased, temporarily, by means of the regulator (lv-that is to say, byincreasing or diminishing the tension of spring It by manipulation ofscrew-cap g. The ale flows into the receiver A until it is full, and itslevel is indicated on gage I3. If it be desired to draw the alesolid-that is, from the receiver-the attendant turns the plug 2 of thefaucet F in the direction indicated by arrow-l2 in Fig. 4, up to thestop, which opens the faucet by way of passage 4, tube 6, and pipe Ewith the receiver A, and the ale flows out through eduction-tube C undera moderate pressure and with little foam. If it be desired to draw ameasured quantity, this will be indicated by the gage B,as the inflow atinduction-tubeM during the process of drawing will be comparativelyinappreciable, and may be ignored. If the ale be too solid or dead 7when drawn as above to suit the purchaser, the attendant may, before`IOO 'up to the stop, and this will have the effect to close the faucetto the receiver and open it to the ale-casl; direct through passage 5,tube 7, and pipe II. rlhis will of course supply the necessary aerationand foam, as will be well understood. lIhus the attendant has it withinhis control to proportion the quantities of ale under high and lowtension to suit the tastes of customers. IVhen required, he may drawwholly directly from the cask.

If it be desired to remove the receiver for cleansing or for repair,this can readily be done without interference with the draft direct atthe faucet F by simply detaching the couplings D and L, having firsttaken the precaution to close cock K. Ihe regulator J may also beremoved by means of the detachable connection of same with pipe H.

In the bottom of receiver A is a screw-plug, a', which may be removedfor convenience of rinsing out the receiver. The glass tube of gage Bmay be readily swabbed out an d rinsed by first removing the screw-cap bat the top of same.

From the above description it will be seen that my apparatus provides aclosed receiver for the ale in lieu of the open measure or pitcherusually employed, thereby avoiding insects, and at the same time keepinga reservoir of the liquor under a reduced gaseous pressure, and not opento the air. As before stated, the attendant may at any time reduce thepressure in the receiver A by manipulation of the cap g of thepressurevalve G. The proper adjustment of the regulators J and G is amatter always within the control of the attendant and subject to hisjudgment.

I usually make the pipe 6 a little larger than the pipe 7, as thepressure in the latter is greater; but this is not essential.

A close receiver with an inlet controlled by a pressure-regulator nearits top and an outlet from near` its bottom is fullyillustrated in myformer patent, referred to; and these features I do not broadly claimherein.

Having thus described my invention, I claim- I. IThe coinbination, withthe receiver provided with au outlet and an inlet and with apressure-regulator arranged between the inlet and the cask from whichthe beer is drawn, of a two-way faucet, a pipe leading to said faucetfrom the outlet of the receiver, and abranched pipe from the beer-Cask,one branch of which leads to said two-way faucet and the other to thereceiver through said pressure-regulator, substantially as set forth.

2. rlhe combination, with a two-way faucet, substantially as described,having two tubes, 6 and 7, whereby it is coupled to the pipes E and H,respectively, of the said pipes, the former connecting the faucet withthe receiver and the latter connecting the faucet with the liquid sourcedirect, the receiver A, provided with an inlet, M, the pipe H', whichconnects the inlet of the receiver with the liquid source, and thepressure-regulator J iu the pipe which supplies the liquid to thereceiver, whereby the attendant is enabled to draw at will liquid fromthe receiver or the liquid source direct 7o through the same faucet.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.

JOHN I). GRUBER.
